GHK-Cu (Copper Peptide)

GHK-Cu (Glycyl-L-Histidyl-L-Lysine), also known as the pretty peptide, is a high-affinity copper-binding tripeptide. It is a primary reagent in studies investigating cellular pathways associated with collagen, fibroblast activity, and genomic expression within the extracellular matrix.

• High-purity copper tripeptide

• Not for human or veterinary use

• Applied in research on collagen-related pathways, fibroblast behaviour, and gene expression

GHK‑Cu is a naturally occurring tripeptide composed of glycine, histidine and lysine, bound to a copper ion. In humans, it is present in plasma, urine and saliva. For research purposes, we provide a synthetic, high-purity version of this peptide. Scientists utilise GHK‑Cu to study the role of copper in enzyme function and genomic stability.

Supporting Research and Key Areas of InterestDermal Research

GHK‑Cu is extensively studied for its role in signalling the production of collagen and elastin in skin cells. In laboratory studies, it is applied to cultured skin cells to observe effects on the extracellular matrix. This is the structural framework that supports skin integrity. Research focuses on its potential to upregulate Type I collagen and glycosaminoglycans, which are critical for tissue strength, elasticity, and hydration.

Vascular Research

GHK‑Cu is used to investigate angiogenesis, the process of forming new blood vessels. Studies examine how the peptide recruits immune cells to sites of injury and interacts with growth factors, such as VEGF (Vascular Endothelial Growth Factor), to support tissue repair and nutrient delivery to cells.

Hair Follicle Research

In hair biology research, GHK‑Cu is studied for its effects on the growth phase of hair follicles. Investigators assess changes in follicle size and dermal papilla cell activity to determine whether the peptide can extend the active growth phase and reduce inflammation around hair roots.

What is Peptide Stacking?

Peptide stacking is the practice of combining two or more peptides within the same research protocol to investigate whether they may influence multiple biological processes at the same time and potentially create a synergistic effect.
